A writing feel improving sheet comprising a base material and a writing feel improving layer with which a touch pen is brought into contact, wherein when a touch pen having a pen tip of 0.5 mm diameter is used to bring the pen tip into contact with a surface of the writing feel improving layer with which the touch pen is brought into contact and the touch pen is then linearly slid at a speed of 1.6 mm/second while applying a load of 200 g to the touch pen and maintaining an angle formed between the touch pen and the surface at 45°, a difference between a maximum value and a minimum value of frictional force generated between the pen tip and the surface is 80 mN or more and 300 mN or less, wherein the frictional force is measured between a point at which a sliding distance is 10 mm and a point at which the sliding distance is 100 mm. The writing feel improving sheet makes it possible to well reproduce the writing feel experienced when writing on paper with a ballpoint pen.

[Problems] Objects include providing a cover film for testing which can be well fixed to a substrate having a groove and with which a material that constitutes an adhesive layer does not invade into the groove and a specimen can be easily stored in the groove, providing a testing member including the cover film for testing, and providing a method of manufacturing the cover film for testing. [Solution] The cover film for testing () comprises a base material (), a hydrophilic coating layer () laminated on a surface of the base material (), and an adhesive layer () partially laminated on a surface of the hydrophilic coating layer () opposite to the base material (), whereby the cover film for testing () has a region in which the adhesive layer () is absent and the hydrophilic coating layer () is exposed.

Cover film for testing, testing member, and method of manufacturing cover film for testing

[Problems] Objects include providing a cover film for testing which can be well fixed to a substrate having a groove and in which a pressure sensitive adhesive does not invade into the groove, providing a testing member comprising the cover film for testing, and providing a method of manufacturing the cover film for testing. [Solution] The cover film for testing () comprises a base material () and a pressure sensitive adhesive layer () laminated on one surface side of the base material (). The cover film for testing () has a region in which the pressure sensitive adhesive layer () does not exist in the plan view.

Cover film for testing, testing member including cover film, and method of manufacturing cover film for testing

[Problems] Objects include providing a cover film for testing that can be well fixed to a substrate having a groove and does not adversely affect the groove, providing a testing member comprising the cover film for testing, and providing a method of manufacturing the testing member. [Solution] The cover film for testing () comprises a base material () and a thermoplastic resin layer () laminated on one surface side of the base material (). The thermoplastic resin layer () constitutes an outermost layer at one side of the cover film for testing ().
